FRANK IK. DAVIS, OF WASHINGTON, DISTRICT F COLOMBIA, ASSIGiNOR, BY MESNE ASSIGNMENTS, TO-ELLIOTT-FISHER COMPANY, OF NEW YORK, N. Y., A COR2ORA- TION OF DELAWARE COMBINED TYPEWBITING, BOOKKEEPING AND CARD-PERFORATING MACHINE 4 Application led July 8,

This invention relates. to a combined typewriting, computing and card-perforating machine, and, generally stated, provides a novel organization wherein a novel card-per- 5 forating mechanism is automatically controlled through the medium of computing .mechanism, to the end that, While items are being accumulated in said computing mechanism, the card-perforating mechanism is 1 automatically caused to be actuated to record some or all of said items in record-cards, said items being thus recorded by means of perforations in said cards. i

The preferred form of the new organizavtion includes the Well-known Underwood- Hanson combined typewriting and computing machine in whichtheoperation of typewriter-keys vmay set up items in computing mechanism, which is below the typewriter and whichcomputing mechanism is then operated y to accumulate said items in one or more registers. As is usual 1n most computing mechanisms, the several digit-numerals of the items are set up in respect to a denominational series of register-bars or the like, each of which may have,- when the item is being accumulated, an individual movement, 'the extent of which depends on thedigit set up in respect thereto. In the Underwood-Hanson machine, eachregister-bar has, extending lengthwise thereof in the direction of its movement, va row of settable digit-pins, by means of which the extent of movement of said bar is determined. Thus it may be said that the digits are set up in said register-bars.

Thenovel card-perforating mechanism includes a nestof digit-punches arrayed in numerous denominational columns, the arrangement of which corresponds to similar columns of digit-spaces ofthe card to be punched. A punch-selectin plunger, pin,'or equivalent device is provided for each denominational column of punches andis individually movable along said column of punchesto the particular digit-punch which is to be selected and rendered effective thereby.

An im ortant feature ofthe invention r'e-' sides in t e'provision of means'tvhereby each punch-selecting device is keyedxto one of the 5 aforesaid register-bars so that the movement 1927.A Serial No. 204,249.

of said bar to accumulate the digit indexed therein automatically serves tol move the punch-selecting device to the corresponding `digit-punch. `The novel card-perforating cumulate at the same time some or all of thev items in registers. In the usual course of the Work the amounts'v accumulated, as indicated 'in the dial-wheelsof the register, are transcriped either to the aforesaid work-sheet or toV other sheets. In combination with the present invention', the Underwood-Hanson computing machine or similar computing lmechanism may also serve to produce perforated record-cards descriptive of said items or data, said cards being thus produced coincidentally With the list` of said items or data upon the aforesaid Work-sheets and with ypracticallynoextra expenditure of labor on the part lof the operator.

The card to be perforated is usually divided into zones, defining the nature of the several items to be recorded therein. Some of the items, as, for example, the diiferent codenumbers used to designate various commodities, departments or similar classificatmns need, of course, not to be accumulated in registers, and are to this extent diferent from items such as 'amounts Whichare to be accumulated.

The Underwood-Hanson computing machine has the usual register-bar pin setting or indexing mechanism controlled by the numeral type-keys, and, by means of said initem by the useof digit-pins in several sets of register-bars orf in any predetermined one or ones of saidv sets of bars, eachset of registerbars being usually associated with a corredexing mechanism, it is feasible to set up an -w serves to select said punchesf and perforation of the card is therefore v'preferably efspending register or accumulator. Thus, one set of register-bars may have all or some of its bars keyed to the aforesaid punch-selecting devices, and, if, as may occur when us- 5' ing the preferred form of the invention, the

several items which are successively set up in said one set of bars are of different orders, the total accumulated Vin a register associated with said one set of bars will be a nondescript amount and may therefore be disregarded. A register is, however, preferablytobe provided with said one set of bars, as there may be forms of work inv which all the items to be recorded on a card are of the same order ,andA are to be accumulated. It isoptional wheth-` er or not the set of pin-bars which are keyedl to the punch-operating devices are vprovided with a register or accumulator, and it will be understood that other registers operated by Underwood-Hanson indexing mechanism,

amounts, while said amounts are caused to be medium of the aforesaid one set of pin-bars. The in-bars for the punches and registers may be indexed by any digit-type-key.

The number of .the aforesaid columns of digit-punches of course does not exceed the number of pin-bars of the set ofbars which `fected in one zone at a time. The number o'f columns of punches may be less than the nu mber of register-bars'of the set to which said columns vare keyed. 'All vthe register-bars that have digits indexed or lset up therein have areciprocatory movement to effect the accumulation of said digits, and are driven in said movement by means of theusual general operator, which may be either hand-operated 'or driven by means of the usual motor, con-l nection between -the motor and the general operator. being established by means con' trolled, either automatically l through the movements .of the typewriter-carriage, oi' by the usual; manu ally-operable key.

Since only one zone of a card at a. time is punched, means are provided in the card-per-- or automatically moving relation with the nest of punches. Theworksheetin the typewriteris also divided into zones which de ne the nature of the items or .data written therein, and it is customary tor operate the usual tabulating-mechanism to- Imovethe typewriter-carriage,s o that'thelsevf eral zones )of the work-sheet are successively broughtnto Vrinting position. -The means provided in t e card-perforator vmechaamism whereby the several zones of thecard are brought intov punching-position include a' 1 card-carriage.- For controlling l the move-v ,ments of` the card-carriage, an escapementmechanism preferably provided and has other sets of pin-bars, as is feasible with the transferred to the record-card through thev which are settable. By means ofsaid escapement-mechanism and its settabie stops,

the card-carriage, which may be propelled by means of a spring-motor, may bring the zones of the' card therein into different predeter- `mined punching positions..-

into printing position by tabulating the typewriter-carriage, so'that a corresponding zone of the card is brought into punching position.V

The card-carriage escapement-mechanism -may be-fso arranged that its operation may be controlled in varlous respects, as, for example,

when it is desired that a card-zone be not skipped while .tabulating the typewriter-carriage to ,write in a zone for which there is no orresponding zone on the card. l l

The cards 'maybe automatically fed by power-driven means from a supply-stack into the perforator-'card carriage, which isdesigned to receive one card at a time.- 4At; the time of receiving a card the card-carriage is in an initial position,'froxn which it is moved stepl by step to bring the various zones of the card into punches.

the card may be causedto befejected from said carriage after the punching of the card therein is completed to the extent desired.

Power-driven means may also be provided for automatically returning the card-carriage to its initial starting position where it 4 may receive anew card." i

unching position under' the eans are alsoprovided so that `'A die-plate co-operates with the nest of ,y

punches, and there is normally a gap between the punching surface of said die-plate and the ends of the unches. lt is within said gap that the car is moved endwise` to bringv its different zones into punching position.

Power-driven punch-operating means may be 5 1 provided for causing the selected punches to penetrate the card, and the punches may be either stripped frolnthe card positively or by suitable springs,- one of whichfmay be applied to each'punch, the latter way of preferred way herein shown.-

.stnppmgthe punches from the card being the The main' Yfeatures of the 4power-driven .means for feeding the cards, one at a time, into the cardcarriage, for operating the punches, andvfor returning the card-carriage to its -initial position, are incorporated in the novel card-perforatormechanism 'y and may` be driven by means o f the same motor and power transmission mechanism that actuatesthe Underwood-Hanson. computing mechanism.

Thus there is avoided the need of providing a separate motor-,drive furthe perforating mechanism. Saidtransmission mechanism of'A the Underwood-Hanson computing' vInachine includes a reciprocatory member for driving the aforesaid general operator, and,

as said reciprocatory member has a harmonic motion, its movement may be used for causing the punches to punch the card, the actual penetration of the card by the punches being so timed that it occurs and is eectedmeans of the aforesaid power-driven punch-operating means at the advance extremity of said motion while the various punch-selecting devices are virtually stationarv or have very little motion, said harmonic motion being impressed upon said punch-selecting devices through the medium 'of the general operator and the aforesaid set of register-bars which are keyed to said punch-selecting devices.

Other features'and advantages will hereinafter appear.

The general arrangement of .the embodi- Yment of the invention is vbest Vseen in Figure 1, which shows an Underwood-Hanson com puting machine of the type shown in numer- 45 ous patents; as, for example, the United States Patent No.j 1,254,627 to F. A. Hart, dated-January 22, 1918; many details, which do not-pertain 'to the invention,being omitted. In the typewriter of said machinethe usual #5 0 keyboard includes numeral-keys.`30, which,

. through the usual type-actions generally indicated by the number 31, may cause types 32 to 'print-againsta plateni33 mounted upon an axle34, journaledinthe sides of the usual y 5.5 'platen-trame 35. Said platen-frame is shiftv able up and down for-case-shifting by means which include a case-shift-fram'e 36 `and a .case-shift-lever of which only the rear' portion-37 is indicated. Said 'platen-frame 35 is 7. 3'- Inounted in a vletter-'feeding carriage 38, y 'which moves to and Afro upon rails 39 and 40,4 saidrails being supported by the typewriterframe 41. rIn Figure 2, there is shown the y l f usual spring-drum 42 for propelling the car- 05 nage and the escapement-mechaism for controlling the letter-feeding steps vof said carriage, said escapement-mechanism being generally indicated by the number 43.

` The Acomputing mechanism of the Under- Wood-Hanson computing machine is below the typewriter and includes lone or moregregisters, 'which are conventionally indicatedV and which have dial-wheels 4-4. Said dialwheels are driven in'one direction only by means of one-way connections, not shown, to racks 45. Said racks are formed on bars 46, which also carry settable pins 47, whereby the extents of movement of the several racks may be determined. As the extent of movement of each bar 46. depends upon the digit to be accumulated by-means of said bar, there are usually provided in each bar nine pins, one for each digit. The lower ends of said pins 47' are normally flush with the lower edge of the bar 46 and thus normally clear the path 35 of a bar 48, which reciprocates to and fro for the purpose of moving the bars46, which will hereinafter be called pin-bars or registerbars. To set a pin 47, it is depressed endwise, causing its lower end to project beyond the 'lower edge of the bar 46 and into the path of the general-operator bar 48. The amount of movement which the registeri bar receives from the movement of the general-operator bar depends, of course, upon which pin is depressed. The return movement of the bars during which., the dial- Wheels 44 are held stationary, by reason of .the aforesaid one-way drive and the usual detenting means (not shown), is also effected by against a stop-plate 50, which also has slots 5.1

that guide the bars at their rear ends. The general-operator bar 48 returns the registerbars to within a short distance of the stopplate 50, the return movement of saidbars being completed by means -of a sprin which cooperates with a nose 53.0n sai barto effect the fullreturn of said bars. In thisj manner, when the bars arefully returned t'hereis left a gap 54 between eachregisterbar-and lthe general-operator bar,said gap 115 permitting thev re 'ster-bar to have an endwise movement su cient tobring its pins into setting positionfin line with thefpin-setting` bars 55' of the usual pin-setting frame, generally indicated by the number 56. Nor- 12 mally, the pins 47 of the register-bars are not directly under the' pin-setting bars 55, but occupy positions in planes vmldway between said bars. Each pin-setting-bar 55 is part of a parallel-motion linkagev actuated bya transy stem 59 depending irqm the Q01-responding 13e digit or numeral key and which moves downwardly whenever said key is depressed. Flgure 4-indicates the arrangement of the aforesaid parallel-motion linkages and the transdepression of the numeral or digit keys.

The register-bars 46.a re moved endwise one by one in denominational order as the typewriter-carriage moves step by step through a predetermined zone; each step serving to bring the pins 47 of a bar in line with the pin-setting bars 55. A register-bar having been brought into pin-setting position, one of its vpins will be depressed or set by operation of a numeral-key, whereupon the typewriter-carriage escapes and takes another. step in which the next bar is moved endwise. while the preceding ,bar, urged by the spring 52, returns to its normal position. For moving the register-bars endwise to pinsetting position 4through the-letter-feeding steps of the carriage, there areprovided. the usual jacks 61 and push-rods 62 at the rear of the typewriter, For each register-bar there is an individual train including a jack, a push-rod, and a lever which is one of a seri es of levers 63 engaged by the lower ends of the push-rods. The typewriter-carriage moves from right to left, and as the register-bars 46 mustbe indexed in order from left to right, there is employed therefore, to transpose the order of impulses which the register-bars 46 receive from the rods 62, a series of transposinglevers 65, each having an arm 66 which engages one ofthe levers 63, and an arm 67 which engages the corresponding registerbar, each of the arms 66 being connectedto acorresponding arm` 67 by a bail 64 (seef Figure 4). The transposing device is of the type 4shown in United States Patent- No. 1,370,-

360 to H. L. Pitman, dated March 1, 1921.

For determining which zones of the carriage-movement are to be eilective to Acause the-pins in the register-bars to be set, there y is'provided for each zone aselec'tor-dog 68 which, in accordance with the location of each zone on a work-sheet, is shiftable and settable along the usual rod 69 and 70 which are mounted on the typewriter-carriage, and

vwhich extend in the direction of travel of said carriage. The selector-dogs have tappets 71 which encounter the forward ends of the jacks 61, and, in displacing'said ends, cause said jacks to rock about their pivots 72. If the 'computing mechanism is provided with more than one register, there is provided a set of jacks 61 for each register, and the array of forward ends of one set of jacks is offset from the array of forward ends of other sets of liacks, the tappets 71 -of the selector-dogs 68 being correspondingly offset. In this manner a selector-dog lmany only co-operate with its own set of jacks. The" selectordogs 68 are tiltable' downwardly about the rods 69, so that the tappets thereon may be withdrawn from the plane of the forward ends of the jacks; such withdrawal being eiected under circumstances, as, for example, while the carriage is being tabulatedby means of the regular decimal tabulator-keys 73, or while the platen is in uppercase position. For holding the selector-dogs 68 in operative position, there is provided the usual frame 75 which carries a roll 76 having conically-shaped ends and supporting the rearward ends of said selector-dogs 68, said dogs having conical rolls 77 which bear upon said rolls 76. There is usually one of said frames 75 and therefore one of said rolls 76 for each set. of jacks, and the selector-dogs are only raised to operative position as the rolls 77 thereon pass over one of the frame-rolls 76. The frames 75 Amounted upon a rockshaft 78. By means of an arm 7 9 lprojecting from the case-shift frame 36, which swings about the axis of a rod 74, the rock-shaft 78 may be rocked to withdraw the dog-supporting' frame-rolls 76 when the platen is moved toupper-case position, said arm 79 co-operating for this purpose witlLan arm 80 extending from said rock-shaft 78. Also, depression of any tabulator-key 73, mounted on a corresponding tabulating key-lever 73, to. raise a tabulating stop 81, causes said rockshaft 78 to be rocked by means of an arm 82 which is operatively connected to said rocklshaft by means of a link 83 and an arm 84,

non-add key (not shown) is operated; saidl key when operated being eiiective to swing a lever 86- of which only a fragmentary portion is shown, said lever co-operating with an arm 87 projecting from said rock-shaft 78. The computing mechanism is in a casing 88, the upper portion of which also serves as a support for the typewriter, said casing being in turn supported upon a plate 89 which is the top platform of the supporting stand for the whole mechanism. l l

` vThe general-operator bar 48 is part of the reciprocatory frame or general operator which includes two racks 90, lone at each side of the casingI 88, the general-operator bar 48V spanning said racks and being supported between plates -91 fastened to the sides `of said racks. Driving connection is made to the left-hand rack at 92 (Figure `1) by a reciprocatory member 93 driven to and fro by a lao crank 94, which is housedand guided within f a transmission casing, generally indicated 13 by the number 95. Said transmission casing 95 also houses the usual reducing gearing and the clutch, neither of which is shown, and whereby saidcrank may be connected to an electrically-driven motor 96. The clutch includesan endwise xovable pin 97 which pro- ]ects above the transmission casing 95' and said endwise movement serves to condition the l'an operating cycle of the computing mechanism may be efectedby depressing the usual manual key 98 to swing a lever 99 downwardly about a fulcrum 100, said lever in `turn rocking a transverse lever 101, theinner end of which engages said pin 97, the latter lever 101 being pivotally supported upon the supporting stand-plate 89eby the usual means not shownin detail.

A computing machine cycle may also be initiated automatically through movements of the typewriter-carriage. Thus,"for eX- ample, as the typewriter-carriage leaves a computing zone, tripping means may be actuated whereby the withdrawal of the clutchpin 97 is effected. Figure 3 shows, in per spective, the usual tripping means, whereby movement of the typewriter-carriage effects withdrawal of the clutch-pin 97; The usual stops 102, settable along the typewriter-carriage, which co-operate with the tabulating stops 81,'are- `each provided with a tappet 103 which displaces the end of a lever 104 and thereby rocks the same about a` pivot 105.-

The rocking of said. lever causes,l by means indicated in Figure 3,v the end` 106 of a-l bar 107 to be withdrawn from the end of aI spring-pressed lever 108 i, which is thereby lrocked v' and which thereby depresses a. verticalslide 109, which in turn rocks the jlever 101 to raise the clutch-pin 97. The tapfas ' pet 103 of the tabulating stop may rock the lever 104 and beclear thereof in one step ofthe typewriter-carriage. The pin 97 need be raised -only for a moment, that is, just long enough torelease the aforementioned clutch-memb'er.- 4

During. a computing machine cycle all digitsset up in the register-bars are accumulated duringl the forward movement of said bars'. All pins 47 that were set `for 'said digits in the register-bars are caused to be restored toward the end ofthe -return movement of said bars, by means of a lflat plate 136, which, by means of the .usual linkage generally indicated bythe member 137, is

` constrained to move upwardly with its surface always parallel to the lower edges of the register-bars ;l the upward movement of said plate serving to restore the pins and being effected by means of a one-way dog 138 pivoted to one of the rack-bars 90,*said dog displacing the end of an arm 139`which is keyed to a shaft 140 and causing said shaft to be rocked. By means of arm 141 keyed to said shaft 140, said pin-restoring plate 136 is raised by the rocking of said shaft. The raising of said plate having just been effected as the racks reach the `end of their return movement,'th e end of the arm 139 drops Y olf the tip-of the dogl38 again, thereby permitting said vpin-restoring plate 136 lto reassume its normal position. In the forward movement of said racks, the tip of the dog 138 is diverted, being displaced by the end of the arm 139 in said forward movement,

said dog being normally but yieldingly held by the spring 142 against a stop144 in the rack 90. During the return movement ofthe register-bar, the usual carryingmechanism i (not shown) becomes operative. Said carrying mechanism is lof the 'type describedim the aforesaid'patent to Hart.

In the means for returning the typewritercarriage by power, there is provided on said carriage a rack which meshes with a pinion 111 rotatable on or with a'shaft 112 journaled in a bracket 113 which is attached to the typewriter-frame 41. Said shaft 112 is driven by the motor 96. For connecting said [shaft tothe motor, there is provided thereon a pulley 114, which, by means of a.

belt 115, is connected to an aligned pulley 116 located below the' plate 89 of the 'supporting stand. A driving pu1ley`117 on the motor-shaft is located as shown in Figure 1,

Vand' is connected to the Vpulley 116 by means u of a jack-shaft 118 which has a pulleyl19 in line with the motor-pulley 117, and which is connected to said pulleyr 117 by a belt 120.

Thus, the shaft 112 rotates'when'the motor 96 v rotates, and rotation of said motor' may thereby serve to return the typewriter-carriage. The carriage-returning pinion 111 is normally operatively disconnected from the shaft'112 and is movable endwise there- '4 along toeect' connectionfor which purpose it is also provided with` clutch-teeth which may cooperate with similar clutch-teeth of a driving member 121which is keyed to said shaft. As the pinion 111 is slid toward said driving member 121, the respective clutchteeth of the driving member and pinion 1nterlock, causing said pinion 111 to rotate and drive the carriage when the shaft 112 is rotated.

For causing the carriage-returning pinion 111 to move intoand outJ of engagement with the toothed member l121, there is provided the usual key-controlled spring-pressed train of linkage, generally indicated by the number 122, one end of which engages a groove inthe carriage-returning pinion 111,

l wardly, and saidlatch-bar is movable u'pwardly suliciently to cause the holding edge of the notch 124 to be freed of the Vplate 125, whereupon the pull of the spring 126 causes the engagement of the carriage-returning pinion 111 with the driving clutch-member,

The usual carriage-return-key 127 on Ithe spring-pressed lever 128 serves to displace the latch-bar 123 upwardly for the purpose of initiating 'a power-driven carriagereturn-movement, said lever being springpressed to yieldingly hold it in normal position.- Said carriage-return-movement is terminated automatically as the carriage reaches the. usual right-hand carriage-stop, not shown in particular detail, b ut which has associated therewith la .dog 129 which is splined to a rock-shaft 130, at the right end portion of which isan .arm A131'. As a camaced tappet 132 mounted upon the typewriter-carriage encounters'said dog 129, the shaft 130 and arm 131 arev caused to be rocked, and their movement is usedto withdraw the carriage-returning pinion 111 from the driving member 121, the withdrawal being eifectedby means of linkage 133 which connects said arm 131 to the-aforesaid train of linkage 122, which servesto move the carriage-returning pinion 111.

The motor 96 is not a continuously running motor when the machine is inoperation, but is only run when-the generaloperator is to be actuated to accumulate an item; or\when the carriage is to be returned. For starting the motor when an item is to be accumulated, there is, within the transmission-casing 95, a switch (not shown) controlled by operation of the manual key 98 when it is pressed to initiate a cycle of the computing mechanism, said switch beingdescribed in the aforesaid patent to Hart.) For starting the motor whenv a carriage-return-movement is to be initiated, and for maintaining the operatingV circuit for said motor independently of the `switch in the transmission-'casing when a 'computing machine `cycle and carriage-return-movement -are initiated simultaneously,

there is provide'danother switch..generally indicated bythe number 134, Figure 1. Saidl switch 'is' caused to be closed by the clutch-'engaging movement of the-train of linkage 122, which movement ensues upon pressing the carriage-return-key 127. In order `that the movement of said linkage may control' said switch, there is the usual controlling link, bal'V orrod 135 extending fromsaid switch to said train of linkage. Said controlling link 135 engages' a spring-pressed 'switch-member and by its endwise displacecardis divided-into zones which define the items to be recorded therein. In said Figurel 15 there is also shown an illustrative worksheet f'in position around the typewriterplaten, said work-sheet being also divided into zones which define the items to be written thereon. As will be shown presently,

some of the items written on the work-sheet are alsoaccumulated m one or more registers of the computing mechanism. Furthermore, while writing theV items on the worksheet, the novel vcard-perforating mechanism is controlled tothe end that s ome or allpf the items written on the work-sheet `will bel recorded in therec'ord-card by means of the perforations 143. 11n the card-perforating mechanism, a'gang or nest of punches 145 is 4provided, said nest of punches being arv ranged in sayv five denominational columns, as herein shown, each column having nine punches` one for each digit. j

The denominational columns of punches extendin a direction which is the same as the, direction of movement of the register-bars, and-it is a feature of the invention that the selection of the punches is controlled bythe` extents of movements of some of the register-bars.- A punch-selecting device which may co-operate with a register-bar is accordingly provided for each denominational col- Y umn of punches said device serving to render effective in said column the punch which corresponds to the digit indexed in the coring device is preferably in the form of an endwise movable slide 147 each slide carrying a plunger 148, which may be made by moving said slide 147 endwise. The lower end of the plunger148 normally clears the upper ends of the punches and is held clear by means of a spring 149 whichnormally retains the plunger in -it's upward position against suitable stopping means which may be in theform of a turned-over .tab 150 reacting against an adjacent edge' of the sliding bar 147` FigurelO); Y

If,` as is in the'computing mechanism herein shown, the intervals or spaces which define the extents of movements of the register-bars lare not the same as the intervals or spaces ionY f to register with anv one of the several punches lll between the punches but are actually some- .bar consists therefore of a lever 151 swinging nected to the slide 147 at a point further from lmovement ofsaid slide.

to the register-bar is to control the The meansconnect ing a punch-selecting slide 147 to a registerabout a fulcrum 152, said lever being conthe fulcrum than is the point to which is connected a link 153V` extending from said lever to the corresponding register-bar. On account-ofthe arc which the first-mentionedpoint describes as the lever swings about its fulcrum, said first-mentioned point is not vdirectly connected to the sliding bar but is connected thereto'by a link 154.V Other means i may be used to connect the slide 147 to corre-V sponding register-bars for simultaneous movements of corresponding but dissimilar extents, as, for example, compoundedpinions and racks, the racks forming part of the slides and register-bars.

.In the computing mechanism herein shown, there are provided three registers, each of which includes eight register-bars. To illus.- trate the invention, the punch-selecting slides 147 are shown as 'being controlled by and connected to the last live bars of the middle register. There may be a column of punches for Y each register-bar, or there may be a smaller number of punch-columnsthanthe live columns herein shown.' As best shown in'Figure 4, the transverse spacing of the columns of punches, that is, 'from column to column,

is less than the transverse spacing of the register-bars, -so that it is necessary to makethe rearward ends of the connecting links 153 converge. It is also desirable that' the nest of punches'be arranged symmetrically, in a transverse direction, in respect to the group of register-bars which control the selection of said punches. The punch-selectingslides 147- may be retained and guided in slotted plates 155 which are incorporated in the general structure of theV perforating mechanism. Cross-pieces 156 attached to said plates may bridge the slides 147 and the slots in which said slides are guided, thereby serving, in conjunction with thebottom of said slots, to retain the slides edgewise.

, The punches 145 have their upper and lower end portions guided respectively in plates 157 and 158, said plates beingV separated by bars 159 which are also incorporated in the general structure of the perforating mecha` said spring.

slides isv zero. As thev crank 94 approaches `naled in opposite plates 256 secured to the tion .being ejfected by means of a. shim 164 between said lower plate 158 and table-surface 161 vand an elevation 165 upon which the forward ends ofthe spacing bars 159 rest (see Figure 9). c For retracting the punches after they have penetrated a card, there is provided for each punch a spring166, the lower end of which reacts against the lower punch-guiding plate 158 and the vvupper end of which reacts against ay shoulder formed by a collar 167 around the body ofthe punch, the opposite shoulder of said collar reacting in turn against the upper punch-guiding plate 157 when said-punch is fully retracted -by It is evident that the several punch-selecting slides 147 with their punch-operating vplungers-148 will have moved to such positions that said plungers. are above certain `punches when Y the computing mechanism register-bars 46, whichcontrol the movements of said slides, have reached the limitof their forward'movements, and it isalso' evidentVV that the punch under-each plunger 148 then corresponds to the pin or digit which was indexed in the corresponding register-bar. At the end ofthe forward movements of the register-bars, the crank, which drives the general operator of the computing mechanism, isA f at dead center in respect to the reciprocatory member 93 which connects said crank to saidgeneral operator, Vso that at the end of the forward vmovement of the register-.bars andi punch-selecting slides 147, the motion of saidf and leaves said deadcenter, it is feasible,

therefore, on account of. said zero-motion, to`

depress the punch-operating plungers-tol effect perforation of the card. The movementof the crank 94, therefore, as'it approaches and leaves said dead center, is used, as best shown in Figure 16, to actuate a train Ofplungerdepressing mechanism which is terminated at one end by -a downwardly movable plate 168V whose surface includes' an area within which the punch-operating plungers`148 move, the other end of said train terminating in a lever 169 pivotally mounted on' the computing mechanism transmission-casing 95 and carrying a roll 170 which,'for displacing said lever, is engagedby the end of the crank 94 as said crank approaches and leaves the aforesaid dead center.

The plunger-operating plate 168 is preferably moved in such mannerthat its surface is always perpendicular, throughout its movement, to the plungers 148 which it serves'to depress. It is accordingly connected toa parallel-motion linkage best shown in Figures 1, 7 and 9. "Said linkage includestwo shafts 171 extending. transversely of the late, each shaft having at one end thereof a ell-crank-lever 17 2, and at the opposite end an arm'173. `Said shafts 171 may be jourouter sides of the punch-frame-bars 159. The .bell-crank-lever-arms which extend in a gener'al horizontal direction and the arms 173 at theopposite ends` of the shafts are pivotally connected to upturned ears 174- of the plunger-depressing plate 168. Downwardly-extending arms of the bell-crank-levers are connected by a link 175, .so that both shafts 171 move in unison, thereby to obtainthe desired parallel motion of the plunger-depressing plate 168. The forwarddbell-crank-lever may have its arm which is connected to the plate 168 prolonged in an extension 17 6, as shown in said Figures 1, 7 and 9, said extension being l5 included in the' previousl -mentioned train of plunger-depressing mec anism, which also includes a j ack-shaft 177 journaled in brackets 178 secured to the top plate 89 of the machine-supporting stand, vas best shown in Figures 1 and 7 Said j ack-shaft 177 serves to transfer the line of action of said train ofy plunger-depressing mechanism from a point opposite the lever 169 to a point below said extension- 176 of the bell-crank-lever 172. There is accordingly keyed to said jack-shaft opposite the lever 169 a downwardly-extending arm 179 connected by alink 180, preferably of adjustable length, to said lever 169.

An arm 181 is also keyed to said jack-shaft at a point below said extension 176 and is connected to said extension by a link-183. By employing the plunger-depressing plate 168, which embraces all the plungers, all 4the punches which areselected by saidplungers lare caused -to punch simultaneously by operation of said plate. A card to be-perforated is therefore punched by zones, that is to say, all the columns of'a zone in which digits of an item are to be recorded by perforations have 40 the perforations effected therein simultane ously' in one operation of the plunger-depressing plate 168, this mode of operatlon being in accord with accumulating the denominational digits of an item simultaneously 'during the reciprocatory movement of the registerbars 46.

The card is, as already stated, divided into item-defining zones, and the means, and the manner of operation thereof, whereby a card is ltaken from a supply-stack and fed transversely of the punches zone by zone, will now be described. Means for'holding asupplystack of blank cards, from which the cards to be perforated may be drawn, include a rearward extension 185 of the table-like surface of the perforator-body-member 162 upon which a stack 186 of blank supply-cards may rest. i The late-ral and rear sides-of the'stack may be retainedby pins 186a projecting upwardly from the surface upon which the stack `of cards rests. The front side of the stack abuts .the throat-block 187, which bears upon the card-supportingl ,surface Aof the. bodymember 162 lonlyat its end portions, so as to afford a narrow aperture 188, which will permit the passage of only one card at a time. The throat-block is cut away or relieved to define the limits l187a of said aperture lengthwise of the throat-block, asshown in Figure supply-stack of aheight corresponding to the height of said pins may be provided for. vThe cards are slid one at a time from the `bottom of the supply-stack and pushed through the throat-aperture 188, so that the leadino' edge of the card may be gripped by 8'0 revoluble upper and lower feed-rolls and 191 which continue the forward movement of the card in a manner to be'presently described. For thus pushing one card at a time towards said feed-rolls, there is provided a recipro- 85 catory card-picking device Whose general construction is substantially the same as similar devices ,that are well known. Said device consists of a member 192 mounted for reciprocatory movement in the perforator- 9o body-member 162 in such manner that a surface 193 thereof is substantially flush with the table-'surface of said body-member. Secured to the rear edge of said reciprocatory member 192 is arpicker-k'nife 194 having a shear- 95 like edge which projects above said surface' 193 to such an extent that -only one card at a time may be picked or pushed from said stack during the forward movement of said device.

. To enable said picker-knife to readily engage 10u' the edge ofthe bottom card, it maybe well to elevate the surface 193 of the card-pickermember 192 slightly, say five thousandths of` an inch,above said table-surface. Said cardpushing reciprocatory member 192 may slide 105' in guidesrformed by depressions 195 in the card-supporting surface of the extension 185 and may be retained in said guides by means of a rod 196, which is held in a downward extension 197 of. said member, and isA guided 110 the punches after said carriage receives a' 12 from the supply-stack. Said carriage is mounted for movement in a direction at right angles to the direction from which vit receives a card from the supply-stack. In the-preferred form of the invention the card-car- 12 riage is of such form that it moves` the card lengthwise by pushing upon one corner thereof, said card-carriage being `therefore pref- .erably in thel form of a' rod 199 having several attachments andr formations to Ybe 130 described, and an upward projection 199a whereby said carriage may push against said corner of the card. As best shown in Figure 19, said projection 199a is formed by a bent-over portionv of a strip 200, which is elevated .sufliciently above the top surface of the carriage 199, as shownv in Figure 12, to form with said surface a card-retaining slit in which a lengthwise edge of the card may be received. When the card-carriage is to receive a card from the supply-stack, it is held in such position, by means to be presently explained, that the projection' 199a is just to the right of a line through the right edge 201 of a card as it isadvanced from the supply stack. By means of a spring-motor 202, Figure 19, and draw band 203, the card-carriage is drawn toward the left to bring its several zones into punching position .under vthe punches. Before describ-ing the means whereby thev card-carriage is positioned for severalv zones, it may be stated at this point that the vupper feed-roll 190 is caused to be rais slightlyto free the card, so that said car may be free to move endwise with the card-carriage after having been advanced by the feed-rolls into position in said carriage.

The means whereby the upper feed-roll 190 is thus raised will also be described presently.

An escapement-mechanism' controlled by operation of the tahulating keys of the typewriter is provided to effect the zone-determining steps of the card-carriage. Said mecha'- nism is controlled vby operation of the tylpe-A at duced to the form of a rod 217, which may be' writer-tabulating keys for the reason t when the typewriter-carriageis tabulated to a new zone, the card is, as arule, also tabu'- lated toa corresponding zone, there being,

. the card-carriage 199, and disposed along the\ the escape however, exceptions, as, for example, when the typewrite'fcarriage is'tabulated for a zone 'on the work-sheet in the typewriter for which there is no corresponding zone in the card. In -such case, the escapement-mechanism ma be operated to move ythe card-carriageid y in a manner which will be explained.

The card-carriage escapement-mechanism includes a number ofl settable stops 205, in the form of pins, which maybe pushed into and retained in any one of a series of holes 206 in upper surface thereof, the holes being spaced the same as the spacing of the denominational columns 'of- .the punches and ofthe card.' A

vibratory dog-member 207 carrying a holdf ing dog-214 and a steppinug dog 215, said dogs bemg'of' the vtype usua y employed in escapement-m'echanisms', cooperatesjwith the stops 205 to hold the carriagein its vseveral zone-determining positions and also to permit ofsald carriage from .POStion to position.' The mode of operation of lsaid rema'y be igure '11,

best understood by reference to which is' a perspective view ofthe escapeperforating mechanism. Whenever a tabulating 4key of the typewriter is operated there is exerted a pull upon a link 210, said pull, through the medium of an arm 211 attached to said link and keyed to a rock-shaft` 212, serving to rock said shaft, so that another arm 213 also keyed to said shaft and having its end pivotally connected to the dog-member 207 may push said dog-member forwardly. The fixed or holdin dog 214 is thereby moved just ahead of and stop 205 was just previously engaged by the spring-pressed stepping dog 215 pivotally mounted upon said dog-member 207. As the fixed or holding do 214 thus moves ahead of a stop 205, the sprlng-pressed stepping dog 215 escapes from said stop, and by its spring 215a is causedto be diverted to the opposite. side of said stop. When the direction of movement of the dog-member 207 is caused lto be reversed by withdrawing the pull on conveniently guided in the plate 155 that guides the front ends of the punch-selecting slides 147. Y A spring 218, which may be applied as shown in Figure 11, causes the dogmember 207 to react against the pull of the link 210 and serves, whenthe pull of said link is withdrawn, to pull said dog-member to its normal position wherein a collar 219 on the against whichever rod 217 formed on said dog-members bears 'l against said plate 155. One end of. said spring 218 is -anchored toa pin220 projecting from the dog-member 207, and the other end of said spring may be anchored to a screw 221, which may 'also serve to secure the arm 213-to the shaft 212.'

In order that a pull may be lexerted upon the link 210 whenever a typewriter-tabulatfing key is operated, said link is connected to 'the arm 82 o fthetypewriter denominational tabulator-mechanism at the rearV of the typewriter.l By means of the universal bar 85I of said tabu1atormechanism,=the outer end of the arm 82 is swung' upwardly every time a denominational stop 81 is elevated by de rsion of al tabulator-key 73, said universe ybar 85Il being operable b any one of the stops 81,'

and-keyed to the roc -shaft 85 to which said arm 82 is 'also keyed. The'upward movement of said end of the arm 82 causesthe aforesaid pull'vupon the link 210. The end
